Several menue setup values use spin button objects with value plus/minus button instead of keyboard value input.
The V1 menues have autorepeat function with a longer time in front of first repeat, then fast reapeats until key is released. Value “Maximum inverter power” increments or decrements in steps of 100 Watts while “Grid setpoint” uses 10 Watt steps only.
For bigger installations, it will take a long time to increase grid setpoint from -30 Watt to - 30 kW. Therefore the V2 gui menues use a progressive autorepeat what becomes faster with the time. This allows big value changes in shorter time. Unfortunately, the autorepeat progression does not stop at a maximum speed or maximum speed is much too high. For this reason, user is not fast enough to release the mouse key at desired target value. Try to change grid setpoint from 1kW to 30kW. Using the V2 menues, it will frequently overshoot at 30kW. Therefore it needs to have one or more stops below 30kW to approximate the correct value.
There are several solutions imaginable. Maybe one of them already exists but I missed while reading the manual.
- User adjustable setup for increment / decrement distance of values
- Pulldown menue with several user defined fix values e.g. 1,5,10,20,30
- User setup for the autorepeat frequency in V1 gui
- User setup for speed limit of autorepeat frequency in v2 gui
- Alternate keyboard method of direct value input
of coarse any combination of the above features. Changing autorepeat or step values in any Venus setupfile will be already sufficient.
